Update: Teixeira (quadriceps) has begun rehabbing the injury, but he's expected to miss at least three weeks due to the injury according to the Dallas Morning News.

Recommendation: That would put him back right before the All-Star break, so a pretty likely scenario has Texas being extra cautious and have Teixeira returning immediately after the All-Star break. Brad Wilkerson will get the bulk of the playing time at first base in Teixeira's absence.
